Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-75S
The AirTAC SAUJ100 Adjustable Cylinder SAUJ100X750-75S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 750mm stroke, 1/2" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.

About the Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-75S
The AirTAC SAUJ100X750-75S is a double-acting double-rod profile cylinder with an external stop screw, letting you shorten the extend stroke on-site by up to 75mm. The nominal 750mm stroke serves as the maximum, yielding a usable extend range of 675 to 750mm. It features a 1/2 inch port, an M20x1.5 rod thread, and 29mm adjustable air cushions.
This extruded aluminum profile barrel is more compact than an ISO 15552 cylinder of the same bore. The -S suffix provides a built-in magnet for CMSG, DMSG, or EMSG sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-75S Is Used
Press Fit Tuning
Allows operators to fine-tune the 675-750mm extend distance on-site for inserting varying bearing depths without swapping actuators.
Variable Diverters
Adjusts the pusher end position dynamically on the line to accommodate different package widths during format changes.
Pallet Stopper
Sets precise stopping points for multiple pallet sizes using the 75mm external stop screw window on a long-stroke assembly.
Is the Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-75S the Right Cylinder?
When sizing this 100mm bore unit against the smaller 80mm option, note the thrust jumps from 2513N to 3927N at 0.5MPa. If 3927N is excessive, the 80mm bore is more efficient. Choose the SAUJ over a fixed SAU cylinder when your machine assembly requires iterative end-position tuning without buying new hardware. Select the 75mm adjust window to dial in the exact extend distance. It supports Basic, FA, and LB mounts, sharing mounting compatibility with the AirTAC SC series. Because the stroke is 750mm, you must use external guides to prevent rod bending and manage side loads.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUJ100 Adjustable Cylinder SAUJ100X750-75S FAQ
At 0.7MPa push is 5497N, and at 0.9MPa it is 7068N. The theoretical max is 801kgf at 1.0MPa. The external stop screw shortens the extend stroke by up to 75mm, giving a usable range of 675-750mm.
The -S suffix means a piston magnet is included for CMSG, DMSG, or EMSG sensors. The cylinder does not hold load on air loss; the piston drifts and the cushion only decelerates. For a held load, use an external rod lock or pilot-operated check valve.
